I'm not sure when this started happening, but groups are not working reliably for me. Most of the time at least one parameter won't work. Mostly volume. In this case volume and mute didn't work. Sometimes I can wake them up by unchecking and checking again. In one case editing didn't work. I've been using Logic for a very long time and have been using groups extensively since they were introduced so I'm not a noob. I've searched the web for answers but haven't found any. Any clues as to what might be going on here?
